Mozilla Firefox is a powerful browser, but like all browsers, its cache can sometimes cause websites to display incorrectly. Clearing the cache is a quick and effective troubleshooting step. This guide shows you exactly how to clear your cache and hard reload a page in Firefox for both desktop and mobile.

2. Go to History and then select Clear Recent History....
3. In the new window, find the Time range to clear: dropdown menu and set it to Everything.
